PHONOGRAPH- TRANSMITTING REPRODUGER.

` Application led March 2,3, 1920.l Serial No. 368,169.

To all whom t may concer/n.:

Be it known that I, OSCAR E. Humano, a citizen of the United States,residing at 624.- 44th` Street, in the borough of Brooklyn, county ofKings, city and State ot New York, have invented a certain new anduseful Improvement in a Phonograph Transmitting Reproducem' and I dohereby declare the following to be a description of my invention, suchas will enable others skilled in the lart to which it appertains to makeand use. same, reference being made to the accompanying drawing, andtothe letters of reference thereon, which forms a part of thisinvention.

This invention relates to phonograph reproducers and particularly todevices of this class adapted to transmit sound vibrations from a recordto telephone receivers, radio apparatus and the like located at apredetermined distance from the reproducer, and the object of thisinvention is to provide an improved device of the class speciedwithwhich circuit wires from a source of electrical supply are connected andthe vibrations of the reproducer being transmitted through j atransmitter diaphragm, granular or ball carbon and through said circuitwires, a' further ,object of the invention is to provide a device of theclass specified which 1s so constructed as to obtain a more noiseless,natural and clear reproduction of the subject of a record throu hsuitable apparatus at a predetermined istance vfrom the reproducer; andwith these and other Objects in view the invention consists in a deviceof the class and for the purpose specified which is simple inconstruction and Operation and eiiicient in use, and which isconstructed and operated as hereinafter described.

The invention is fully disclosed in the following specification, ofwhich the accom-` panying drawing forms a part, in which the separateparts of my improvement are des-v4 ignated by suitable referencecharacpin each of the views, andin which I if Fig. 1 is a verticalsection of a reproducer made according to my invention;

Fig. 2 a front view of the reproducer shown in Fig. 1g and,

Fig. 3 a pers ective detail view of a part of the construction shown inFig. 2.v

In the drawing I have shown. at' 1 the casing of a reproducer whichiscup-shapedein.l

form or provided on one side face 'thereof with a recess in which adiaphragm 2 is mounted and spaced between gaskets held in place by 'anannular retaining ring 4.

A stylus or needle holder 5 having an aperture 6 is pivotally mounted ininsulatingblocks 7 mounted in connection with the casing 1. The blocksl7 will be composed of such insulating material as to insulate themounting of the stylus holder 5 in connection with the casing 1, ashereinafter set out.

Thel holder 5 is adapted to detachably support a stylus or needle 8 asindicated in the drawing. y

The upper end of the holder 5 is provided with a contact pin 9 whichpasses through the diaphragm 2and cooperates withpball carbon 9a. Acontact wall 10 is mounted in the casing 1 inwardly of the diaphragm 2and an insulated circuit wire is passed through casing 1 and isconnected with the pin 9 of the stylus holder 5. Another circuit wire12is passed into the casing 1, as clearly shown in Fig. 1, and indicatedin Fig. 2.

The insulated blocks 7 are provided'with lcontact points 14 composed oflead or a composition of lead and other material, and these points passinto the aperture 6 of the holder 5 and form bearing or pivot membersfor said holder. Centrally of the'back of the casing 1 is a projectingstud 15 by means of which the reproducer may be mounted in connectionwith a Asuitable support.

The distinctive feature of my .invention consists in providing areproducer of the class and for the purpose specified with a stylus orneedle holder which is so mounted in connection with the reproducercasing as to be insulated therefrom, as well as the mounting of saidhold-.er onsuch pivots as to eliminate the harsh reproduction of thesound wavesof a record, ywhereby a selection on a record may bereproduced through a suitable apparatus located at a predetermineddistance from my improved reproducer, the vibrations being-transmittedthrough the electric circuit wires 11 and 12. f

i Having fully described my invention, what I clailt'i gislnew anddesire to secure by TJEtteIS Patent, 1S v I A reproducer ofthe classdescribed comprising4 a casing, a diaphragm mounted therein. a contactinsaid casing inwardly of said diaphragm, a stylus holder pivotallymounted in blocks on said casing, said holder being provided with acontact pin which is secured centrally of said diaphragm and electricwires passing into said casing and one of which is secured to saidcontact pin, name to this specification in the presence of the pivotalconnection of said stylus holder two subscribing witnesses. with saidblocks being made by lead pivots A for the purpose of eliminating theharsh re- OSCAR E.
